Application filed March 10, 1914:. Serial No. 823,775.

To'aZZ whom #may concern.'

Be it known that I, ELMER WrsEMAN, a citizen of the United States,residing at Milwaukie, in the county of Clackamas and State of Oregon,have invented new and useful Improvements in Tack- Pullers, of which thefollowing is a specification.

This invention relates to tack pullers; and it has for its primaryobject the provision of a simple device of this character which willconsist of gripping devices mounted for relative movements and adaptedto be effectually moved into gripping engagement with the head of thetack when pressure in a downward direction is applied to the device.

Another object of the invention is the provision of a device of thischaracter which will consist of relatively adjustable gripping devicesand means for securing the devices in locked positions when engaged withthe head of the tack and for subsequently releasing the members topermit the tack to be released from therebetween.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts, aswill be hereinafter described and claimed. o

In the accompanying drawings Figure 1 is a longitudinal sectionthroughthe device, showing the gripping members in their normal positions; Fig.2 is a similar view, showing the gripping members in active grippingpositions; Fig. 3 is an inverted perspective view of the device; andFig. 4; is a transverse section therethrough.

The device consists of a handle V1 which may be constructed ofwood,'metal or the like. The handle is provided with a bore 2 closed atone end, as at 3, and open at its opposite end, as at 4. Within the borean extracting device 5 is mounted to slide in a longitudinal directionand it is preferred to form this device from a single length of springysheet metal bent upon itself to provide companion gripping members 6 and6 which are provided with portions normally arranged in parallelrelation to each other and lying in the bore 2. The said members of thedevice are connected with each other by a curved upper portion 7 againstwhich one end of a spring 8 is engaged. The opposite end of the springbears against the closed end 3 of the bore 2 and under the action of thespring the device 5 is normally held in the position shown in Fig. l.

A pm 9 extends through the handle and Vthrough the space between themembers 6 in opposite directions, as at 10 and they are terminallyprovided with notches 11, which are adapted to embrace the shank of thetack. Under the inherent action of the metal from which the device isformed the bulged or curved portions 10 are adapted to be normallyextended or separated from each other for a distance to permit of theirproper accommodation of the head of the tack. The said portions 10 arealso extend ed laterally of the bore to such an extent that when thedevice 5 is moved in a longitudinal direction toward the closed end 3 ofthe bore 2 the edges 12 of the walls of the bore will be brought to bearagainst the portions 10, so as to cause said portions to be moved intogripping positions.

In using the device, the portions 10 are placed over the head of thetack. Pressure in a downward direction is then applied to the handle 1.When moving the handle in this manner the surface 12 of the walls of theboro engage the portions 10 of the members 6 and 6 and the shank of thetack is thereby finally embraced by the notches 11. In order that theportions 10 may be locked in this position during the extracting0peration, the portion 10 of the member 6 is provided with a keeper slot13 which is adapted to receive the effective locking end 14 of a pivoteddog 15. This dog is provided with an extension 16 which is adapted to beengaged by the adjacent member 6 of the device 5, so that on movement ofthe handle 5 in a downward direction the end 14 will be made to springinto the keeper slot 13. This dog is provided with a releasing lug 17,which extends through a passage 18 in the handle. This lug may bepressed by the hand and the dog may be rocked to cause the end 14thereof to free itself from the :sov

passage 13. Instantly on this operation the portions 10 of the members 6and 6 of the extracting device will be returned to their normal extendedpositions under the action of thev spring 8 and the device as a whole,thus set for a subsequent operation of extracting the tack. handle l isembraced by a metal ferrule 19 When the handle is constructed of wood.A

I claim In a tack extractor, a handle having a Genie@ 0f this. patentmay bc Obtained .for

The lower end of the the gripping element from the open end of 20 Y Vthehandle, anda catch to lock the gripping element inthe handle when in Ygfppmg, retracted position.

In testimony whereof I aix my signature in Prese/IIC@ 0f two witnesses.ELMER wisEMAN.
